In
2004, Nobita Nobi is a fourth grader who constantly gets failing grades in his
subjects due to his laziness and is always bullied by his classmates Suneo
Honekawa and Takeshi Goda. His great-great grandson from the 22nd century (year
2136), Sewashi, who watches him every day, travels to Nobita's timeline while
bringing along his robotic cat Doraemon. Sewashi reveals that if Nobita keeps
up his act, he will have a disastrous future: he will marry Gian's sister
Jaiko, have his private company burned down, and will be left with a great
debt. To circumvent this, he orders Doraemon to help Nobita, modifying
Doraemon's nose to prevent him from returning to the future unless Nobita gains
a better future.
Being reluctant until the threat, Doraemon introduces his gadgets to help Nobita which helps him immensely. Though Doraemon warns Nobita not to be too dependent on his gadgets, Nobita asks Doraemon to help him woo his crush Shizuka "Sue" Minamoto whom Doraemon reveals is the one Nobita will marry if his future is corrected. However, all his efforts end up making Shizuka becoming closer to ace student, Hidetoshi Dekisugi. Nobita's attempt to be equal with Dekisugi by studying harder is futile and he decides to let go of Shizuka to make her happier. Mistaking him planning to commit suicide, Shizuka arrives at the Nobi residence and resists Nobita's people-repelling potion to help him which Doraemon reveals is the first step in Nobita and Shizuka's growing relationship to eventually becoming a couple.
Upon seeing his older self rejecting Shizuka's invitation to a
mountain climbing, Nobita disguises himself as his older self to help Shizuka
whom he thinks is separated from her group during a heavy blizzard. His efforts
to help Shizuka do more hurt to himself, but this makes Shizuka feel that she
has to accompany Nobita saying "yes" before collapsing from cold she
contracted from her earlier conversation with Nobita. Forcing himself to
remember the moment, the two are rescued by Nobita's older self who recalled
the memory. Nobita learns from his older self that Shizuka was answering to the
latter's proposition to marry her which means that the two will indeed marry.
After hearing that Shizuka's father has also accepted his daughter's spouse,
Nobita and Doraemon return to the present timeline.
As Nobita's future has changed for the better, Doraemon's
programming commands him to return to the future in 48 hours. Noticing that
Doraemon has a hard time to leave due to his worry for Nobita, Nobita confronts
and have a brutal fight with Gian to prove that he is able to defend himself
without Doraemon. Seeing that Nobita refuses to give up, Gian forfeits as
Doraemon tearfully takes Nobita home before leaving in peace the next day.
During April Fools, Nobita is tricked by Gian into believing that Doraemon has
returned. In anger, he drinks a solution Doraemon gave to him which turns all
lies into truth and vice versa. Finishing his retribution against Suneo and
Gian, Nobita goes back home while lamenting that Doraemon will never return. To
his surprise, Doraemon suddenly returns and tells Nobita that he got permission
to stay with him because Nobita said that Doraemon would never return, still with
the effects of the potion, and it became a truth. They both hug and cry in
happiness.
